滑石(Talc)

         滑石是一种常见的硅酸盐矿物，通常呈白色、浅黄色或淡绿色，具有滑腻的手感。它的硬度很低，莫氏硬度为 1 - 1.5，具有良好的绝热性、绝缘性和化学稳定性，广泛应用于陶瓷、造纸、涂料、塑料、橡胶等工业领域。

Talc is a common silicate mineral, usually white, light yellow or light green in color, and has a slippery feel. Its hardness is very low, with a Mohs hardness of 1-1.5. It has good thermal insulation, electrical insulation and chemical stability, and is widely used in industrial fields such as ceramics, papermaking, coatings, plastics, and rubber.
